Clementine Nutrition Calculator — Per-Fruit Calories, Vitamin C & Folate

One clementine (FDC 173932) weighs approximately 74g and delivers exactly 35 calories — making it one of the most predictable per-unit calorie foods in the fruit category. No weighing, no guessing: 1 clementine = 35 kcal, 2 = 70 kcal, 3 = 105 kcal. This precision is why clementines are uniquely practical for calorie journaling ^[1].

Per 100g, clementines have 47 calories with 0.85g protein, 0.15g fat, and 12.02g carbohydrates — of which 9.18g are natural sugars and 1.7g is fiber. The calorie density is 11% lower than tangerines (53 kcal) and identical to oranges (47 kcal), though the smaller size means each fruit has roughly half the calories of a medium orange ^[1].

The seedless, easy-peel design (Citrus x clementina is specifically bred for this) means the entire fruit is edible portion — there's no core, no seeds to discard, and minimal pith waste. This translates to more consistent weight-per-fruit than other citrus: clementines vary less in size than oranges or tangerines ^[1][2].

Clementines provide 48.8mg vitamin C per 100g (54% DV) — nearly double the tangerine/mandarin average of 26.7mg. One clementine delivers about 36mg vitamin C (40% DV), and two clementines provide 72mg (80% DV) — approaching a full day's requirement from a 70-calorie snack ^[1].

This vitamin C advantage is significant: clementines are essentially on par with oranges (53.2mg) for vitamin C density, while most other mandarin varieties fall well below. The USDA's separate entry for clementines (FDC 173932 vs FDC 169105 for tangerines) reflects this measured difference — they are not nutritionally identical despite being closely related ^[1].

Folate at 24mcg per 100g (6% DV) is another standout — 50% higher than the tangerine entry (16mcg). Two clementines provide about 36mcg folate (9% DV), making them a better folate contributor than most citrus fruits per serving ^[1].

Three clementines (~222g) deliver: 104 calories, 1.89g protein, 26.7g carbs (20.4g sugar, 3.8g fiber), 108mg vitamin C (120% DV), 67mg calcium, 393mg potassium, and 53mcg folate (13% DV). One medium orange (~131g): 62 calories, 1.3g protein, 15.4g carbs (12.2g sugar, 3.1g fiber), 69.7mg vitamin C (77% DV), 52mg calcium, 237mg potassium, 40mcg folate (10% DV) ^[1].

Three clementines cost 68% more calories but deliver 55% more vitamin C, 29% more calcium, 66% more potassium, and 33% more folate than one orange. Per calorie, the three-clementine serving is actually more nutrient-dense for every measured micronutrient except vitamin C per kcal (where they're roughly equal) ^[1].

The portion psychology matters: people typically eat 2-3 clementines in a sitting because each one is small and the peeling-eating rhythm encourages consumption. This often means a larger total intake than a single orange — which can be positive (more nutrients) or a consideration for sugar tracking (20.4g sugar from three clementines vs 12.2g from one orange) ^[1].

Clementines provide 0.636mg niacin (B3) per 100g (4% DV) — nearly double the tangerine value (0.376mg) and higher than most citrus fruits. Three clementines deliver 1.41mg niacin (9% DV), a meaningful B3 contribution from fruit. This likely reflects the specific cultivar characteristics of clementine breeding lines ^[1].

Thiamine (B1) at 0.086mg per 100g is also above the mandarin average (0.058mg) — a 48% increase. While these B-vitamin levels are modest individually, they contribute to the overall nutrient density that makes clementines nutritionally distinct from their tangerine and mandarin relatives ^[1].

Potassium at 177mg per 100g (4% DV) is the highest among the mandarin group (tangerine: 166mg, general mandarin: 166mg) and approaches orange levels (181mg). Three clementines deliver 393mg potassium — about the same as a medium banana (422mg) but spread across a much lower calorie count (104 vs 105 kcal) ^[1].
